| Abstract: | In this work, the liquid - liquid equilibria (LLE) data of ternary mixtures 2-butanone -toluene -water at 303. 15 and 323. 15K, 2-butanone -4-methyl -2-pentanone -water at 293. 15, 303. 15 and 313. 15K, 2-butanone - cyclohexanone -water at 293. 15 and 313. 15K were measured experimentally. NRTL equation was used to correlate the experimental data. The equation parameters for the partially miscible pairs and the miscible pairs were obtained from binary and ternary LLE data respectively. The evaluation results all a-greed well with the experimental data. |
